This paper describes MultiMedia MedNet (MedNet), a distributed collaborative medical multimedia system. MedNet combines neurophysiological, audio and video data in a real-time remote diagnostic and monitoring system, and is used on a daily basis in seven hospitals at the University of Pittsburgh Medical Center. MedNet provides an interesting example of a working distributed and collaborative multimedia system in an exacting environment, involving data types and manipulations that are broader and more demanding than those found in a typical teleconferencing application. Phase I MedNet incorporates digital signal processing, along with distributed systems tools for group communication, multimedia file access and storage, and software for the manipulation and display of neurophysiological information. Communication control in Phase II is managed by a multimedia group process protocol called the Distributed InterProcess Communication System (DIPCS) that is scalable to a WAN.
